Title: Process for making formed flexable plastic foam products
Inventor: MENARD MICHAEL J
IPC: A61F13/15
Filed: 1987-08-14
Granted: 1989-12-21
Abstract: A process for making a formed flexible plastic foam product containing a fibrous web insert. In the process, a flexible ethylene containing sheet material is rapidly heated and die formed to provide multiple parallel shells integrally attached to the sheet. A fibrous web material having an elongated corrugated shape is filled with an absorbent powder, and is die cut to individual desired shapes which are inserted into the shells. A thin fibrous facing sheet material is placed over the powder-filled web and formed shell and the facing sheet is heat sealed onto the foam shell perimeter, after which the formed and filled foam shells are die cut from the plastic foam strip to produce the individual formed products. The process advantageously provides increased production rates at 10-30 cycles/minute for the formed products.

Inventor: BOSLEY J A DEHNEL R B SYMIEN S
IPC: C05G3/80
Filed: 1982-08-05
Granted: 1985-10-31
Abstract: Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water.

Title: Digital demodulator for phase modulated signals - samples modulated carrier digitally and compares amplitude swing about null
IPC: H04L27/233
Filed: 1970-08-12
Abstract: A digital scanning circuit provides a demodulation circuit for phase modulated signals at high transmission rates. The carrier signal is sampled at a rate given by a formula which includes the number of samples per half period. At each sample point a check is made of whether the carrier modulated signal is positive or negative amplitude. The modulated signal is coupled over a threshold gate to provide a square wave input for a shift register comprised of flip-flops. The signals are gated in by a clock input signal also squared by a gating element. Successive values of the samples within a half wave period are entered into the shift register. Four flip-flops arranged as a ring counter track the sample point and four more flip-flops control the activation of gating circuit elements. The two output gates provide a signal '0' or '1' by comparison of successive scanning values.

Title: Voltage controller for HV DC converter station - uses ideal no load voltage as reference for transformer tap changer regulation
IPC: H02J3/36

Abstract: By using the ideal rectifier or inverter no load direct voltage as the reference the frequency of operation of the onload tap changer of the converter transformer can be reduced and its useful life thus prolonged. Also a more uniform operation of the converter results. This reference is compared with an ideal no load direct voltage obtained from the actual ac line voltage to form an error sinal. The reference can also be corrected for the d.c. inductive volt drop due to load to give a more accurate value.
